What is Wiring Synthesis?

Wiring synthesis is a transformative technology for vehicle wiring design. Using principles of Model Driven Systems Engineering (MDSE), wiring synthesis automatically generates detailed vehicle wiring design data from simpler, higher level inputs. Totally different from traditional wire routing, wiring synthesis addresses key domain problems such as high frequency design change, arduous configuration management, design quality and verification, and development cost and cycle time. Supported by ten years of software development, major automotive OEMs and suppliers in Europe, USA and Asia have now applied wiring synthesis technology with great success. As electrical complexity continues to grow, wiring synthesis will become the only practical way to design automotive electrical systems.

Optimizing Automotive Wiring Designs Using Engineering Design Automation

Currently, most methods for optimizing an Electrical Distribution System employ unsophisticated and manual spreadsheet tools. Any detailed feedback on critical metrics such as cost or weight typically relies on another organization and requires weeks or months. The resulting EDS is inevitably sub-optimized, not due to a lack of engineering ability, but rather the tools available. To ensure that the EDS design is optimized from the outset, the design environment itself must be enhanced. This paper will discuss the four key requirements for an EDA system along with the flow implications using examples from the Mentor Graphics Capital suite.

Technology To Speed Wire Harness New Product Introduction

The speed with which wire harness makers can bring new or changed designs into production is a key business differentiator. Up until now, the complex sequence of tasks necessary to accomplish such a feat was poorly supported by COTS software. A robust COTS solution from Mentor Graphics is now available. This paper focuses on a set of manufacturing disciplines and describes key “building blocks” which underpin Mentor’s robust software solution for harness wire manufacturers. The Mentor approach protects company IP, reduces manufacturing engineering costs, improves process quality, and provides early and accurate visibility of gross margins. More importantly, it removes critical path bottlenecks to new product introduction.

Symbolic Techniques for Model Code Optimization: FMI Applications

Since its inception, the FMI standard has become the primary method for model transfer and co-simulation, providing a smooth, error-free technique for design engineers to deliver their work without manual integration or resorting to other proprietary tools. At the same time, advanced symbolic technologies have emerged that provide extremely fast auto-generated code for the implementation of dynamic system models and enable advanced analysis applications. This paper describes symbolic techniques employed under the hood for dynamic system model formulation and optimized code generation. One application where the FMI standard has been used is for generating a functional mockup of an automatic transmission from MapleSim, and implementing it in dSPACE's SCALEXIO to perform a full-vehicle, real-time simulation.

Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.

Designing a Phased Array Antenna Using Antenna Magus and CST STUDIO SUITE

Antenna synthesis lets engineers investigate many potential designs and produce antennas that fit the specifications quickly. For effects that cannot be accounted for analytically such as edge effects and mutual coupling, full-wave 3D simulation can complement synthesis tools and allow designs to be checked and fine-tuned. This article explores the synthesis of an antenna array, using a phased array satellite communications antenna as an example.
